Description

The strain gauge load cell FLINTEC RC3 is designed to convert mechanical deformation during compression into a proportional electrical signal.

It consists of an elastic element, a set of strain gauges assembled into a bridge circuit (Wheatstone bridge), and thermal compensation elements for normalizing the output signal.

Operation in harsh industrial conditions is ensured by a stainless steel case, made in the form of a rigid cylindrical shell, and a high protection class (IP68).

It is used mainly for the manufacture/modernization of automobile, carriage, and also multi-ton platform scales of the III accuracy class according to GOST 29329 and RM MOZM No. 76.

Features of FLINTEC RC3

  • High quality manufacturing: total factory control of welding seams by pumping a gas mixture (helium) into the body and subsequent leak detection.
  • Unique cavity separation design: provides for hermetically sealed replacement of the sensor strain cable if damaged; IP68 dust and moisture protection is maintained for the entire structure.
  • High impedance input impedance.

Options

  • High temperature version (up to +120°C) with Teflon cable.
  • Explosion-proof design of the “intrinsically safe circuit” type in accordance with ATEX.
  • Connecting the “screen” core to the sensor body.
